This paper describes a thyristor based static frequency converter (SFC) to run a large synchronous machine installed at a short circuit test laboratory. Normally a synchronous machine requires prime mover or some other driving mechanism to run. This machine doesn’t need a prime mover as it operates in dual mode. In the beginning SFC starts this machine as a motor to achieve the full speed. Thereafter whenever required it can be converted to generator mode. This paper begins with the various starting methodology of synchronous machine. Detailed of SFC with different operational modes have been analyzed. Shaft voltage is a very common phenomenon for the machines with static drives. Various causes of shaft voltages in perspective with this machine are the main attraction of this paper.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Capacitive%20coupling" title="Capacitive coupling">Capacitive coupling</a>, <a href="https://publications.waset.org/search?q=electric%20discharge%20machining" title=" electric discharge machining"> electric discharge machining</a>, <a href="https://publications.waset.org/search?q=inductive%20coupling" title=" inductive coupling"> inductive coupling</a>, <a href="https://publications.waset.org/search?q=Shaft%20voltage" title=" Shaft voltage"> Shaft voltage</a>, <a href="https://publications.waset.org/search?q=static%20frequency%20converter." title=" static frequency converter.

Under certain conditions the converter operates in discontinuous conduction mode (DCM). Inductor current starts from zero in each switching cycle as the switching frequency is constant and not adequately high. A DC-to-DC buck converter is modelled and simulated in this paper under DCM. Effect of ESR of the filter capacitor in input current frequency components is studied. The converter is studied for its operation under input voltage and load variation. The operating frequency is selected to be close to and above audio range. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Buck%20converter" title="Buck converter">Buck converter</a>, <a href="https://publications.waset.org/search?q=Discontinuous%20conduction%20mode" title=" Discontinuous conduction mode"> Discontinuous conduction mode</a>, <a href="https://publications.waset.org/search?q=Electromagnetic%20Interference" title="Electromagnetic Interference">Electromagnetic Interference</a>, <a href="https://publications.waset.org/search?q=Pulse%20Skipping%20Modulation." title=" Pulse Skipping Modulation."> Pulse Skipping Modulation.</a> </p> <a href="https://publications.waset.org/13883/pulse-skipping-modulated-dc-to-dc-step-down-converter-under-discontinuous-conduction-mode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13883/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13883/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13883/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13883/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13883/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13883/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13883/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13883/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13883/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13883/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13883.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">4930</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2511</span> Simulation of Static Frequency Converter for Synchronous Machine Operation and Investigation of Shaft Voltage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Arun%20Kumar%20Datta">Arun Kumar Datta</a>, <a href="https://publications.waset.org/search?q=M.%20A.%20Ansari"> M.

SFC has a feature of four quadrant operations. By virtue of this it can be implemented to run a synchronous machine either as a motor or alternator. This dual mode operation helps a single machine to start & run as a motor and then it can be converted as an alternator whenever required. One such dual purpose machine is taken here for study. This machine is installed at a laboratory carrying out short circuit test on high power electrical equipment. SFC connected with this machine is broadly described in this paper. The same SFC has been modeled with the MATLAB/Simulink software. The data applied on this virtual model are the actual parameters from SFC and synchronous machine. After running the model, simulated machine voltage and current waveforms are validated with the real measurements. Processing of these waveforms is done through Fast Fourier Transformation (FFT) which reveals that the waveforms are not sinusoidal rather they contain number of harmonics. These harmonics are the major cause of generating shaft voltage. It is known that bearings of electrical machine are vulnerable to current flow through it due to shaft voltage. A general discussion on causes of shaft voltage in perspective with this machine is presented in this paper.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Alternators" title="Alternators">Alternators</a>, <a href="https://publications.waset.org/search?q=AC-DC%20power%20conversion" title=" AC-DC power conversion"> AC-DC power conversion</a>, <a href="https://publications.waset.org/search?q=capacitive%20coupling" title=" capacitive coupling"> capacitive coupling</a>, <a href="https://publications.waset.org/search?q=electric%20discharge%20machining" title=" electric discharge machining"> electric discharge machining</a>, <a href="https://publications.waset.org/search?q=frequency%20converter" title=" frequency converter"> frequency converter</a>, <a href="https://publications.waset.org/search?q=Fourier%20transforms" title=" Fourier transforms"> Fourier transforms</a>, <a href="https://publications.waset.org/search?q=inductive%20coupling" title=" inductive coupling"> inductive coupling</a>, <a href="https://publications.waset.org/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/search?q=Shaft%20voltage" title=" Shaft voltage"> Shaft voltage</a>, <a href="https://publications.waset.org/search?q=synchronous%20machines" title=" synchronous machines"> synchronous machines</a>, <a href="https://publications.waset.org/search?q=static%20excitation" title=" static excitation"> static excitation</a>, <a href="https://publications.waset.org/search?q=thyristor." title=" thyristor."> thyristor.</a> </p> <a href="https://publications.waset.org/9997992/simulation-of-static-frequency-converter-for-synchronous-machine-operation-and-investigation-of-shaft-voltage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9997992/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9997992/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9997992/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9997992/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9997992/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9997992/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9997992/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9997992/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9997992/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9997992/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9997992.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">6059</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2510</span> A ZVS Flyback DC-DC Converter using Multilayered Coreless Printed-Circuit Board(PCB) Step-down Power Transformer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Hari%20Babu%20Kotte">Hari Babu Kotte</a>, <a href="https://publications.waset.org/search?q=Radhika%20Ambatipudi"> Radhika Ambatipudi</a>, <a href="https://publications.waset.org/search?q=Dr.%20Kent%20Bertilsson"> Dr. Kent Bertilsson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The experimental and theoretical results of a ZVS (Zero Voltage Switching) isolated flyback DC-DC converter using multilayered coreless PCB step down 2:1 transformer are presented. The performance characteristics of the transformer are shown which are useful for the parameters extraction. The measured energy efficiency of the transformer is found to be more than 94% with the sinusoidal input voltage excitation. The designed flyback converter has been tested successfully upto the output power level of 10W, with a switching frequency in the range of 2.7MHz-4.3MHz. The input voltage of the converter is varied from 25V-40V DC. Frequency modulation technique is employed by maintaining constant off time to regulate the output voltage of the converter. The energy efficiency of the isolated flyback converter circuit under ZVS condition in the MHz frequency region is found to be approximately in the range of 72-84%. This paper gives the comparative results in terms of the energy efficiency of the hard switched and soft switched flyback converter in the MHz frequency region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Coreless%20PCB%20step%20down%20transformer" title="Coreless PCB step down transformer">Coreless PCB step down transformer</a>, <a href="https://publications.waset.org/search?q=DC-DCconverter" title=" DC-DCconverter"> DC-DCconverter</a>, <a href="https://publications.waset.org/search?q=Flyback" title=" Flyback"> Flyback</a>, <a href="https://publications.waset.org/search?q=Hard%20Switched%20Converter" title=" Hard Switched Converter"> Hard Switched Converter</a>, <a href="https://publications.waset.org/search?q=MHz%20frequencyregion" title=" MHz frequencyregion"> MHz frequencyregion</a>, <a href="https://publications.waset.org/search?q=Multilayered%20PCB%20transformer" title=" Multilayered PCB transformer"> Multilayered PCB transformer</a>, <a href="https://publications.waset.org/search?q=Zero%20Voltage%20Switching" title=" Zero Voltage Switching"> Zero Voltage Switching</a> </p> <a href="https://publications.waset.org/11457/a-zvs-flyback-dc-dc-converter-using-multilayered-coreless-printed-circuit-boardpcb-step-down-power-transformer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11457/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11457/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11457/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11457/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11457/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11457/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11457/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11457/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11457/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11457/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11457.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">4244</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2509</span> Comparison of Frequency Converter Outages: A Case Study on the Swedish TPS System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Y.%20A.%20Mahmood">Y.

Suppose, if we are using the RL load the power factor will be reduced due to the presence of total harmonic distortion in the current wave. To improve the power factor the current waveform should follow the fundamental component of the voltage waveform. These can be achieved by using the high -frequency power converter. Based on the resonant circuit the converter is able to perform the function of Buck, Boost, and buck-boost converter. Here ,we have used Buck-Boost converter, because, the buck-boost converter has more advantages than the boost converter. Here the switching action of the power converter can  take place by using the external zero comparator PFC stage control. The power converter consisting of the resonant  circuit which is used to control the output voltage gain of the converter. The power converter is operated at a very high switching frequency in the range of 400KHz in order to overcome the switching losses of the power converter. Due to  presence of high switching frequency, the power factor will improve. Therefore, the total harmonics distortion present in the current waveform has also reduced. These results has generated in the form of simulation by using MATLAB/SIMULINK software.  Similar to the Buck and Boost converters, the operation of the Buck-Boost has best understood, in terms of the inductor's "reluctance" for allowing rapid change in current, which also reduces the Total Harmonic Distortion (THD) in the input current waveform, which can improve the input Power factor, based on the type of load used.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Buck-boost%20converter" title="Buck-boost converter">Buck-boost converter</a>, <a href="https://publications.waset.org/search?q=High%20switching%20frequency" title=" High switching frequency"> High switching frequency</a>, <a href="https://publications.waset.org/search?q=Power%20factor%20correction" title=" Power factor correction"> Power factor correction</a>, <a href="https://publications.waset.org/search?q=power%20factor%20correction%20stage%20Regulation%20stage" title=" power factor correction stage Regulation stage"> power factor correction stage Regulation stage</a>, <a href="https://publications.waset.org/search?q=Total%20harmonic%20distortion%20%28THD%29." title=" Total harmonic distortion (THD)."> Total harmonic distortion (THD).</a> </p> <a href="https://publications.waset.org/10004602/power-factor-correction-based-on-high-switching-frequency-resonant-power-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10004602/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10004602/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10004602/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10004602/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10004602/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10004602/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10004602/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10004602/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10004602/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10004602/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10004602.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1362</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2507</span> High-Voltage Resonant Converter with Extreme Load Variation: Design Criteria and Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jose%20A.%20Pomilio">Jose A.

This paper considers applications in which the load (resistive) has an unpredictable behavior, changing from open to short-circuit condition faster than the output voltage control loop could react. In this context, to avoid overvoltage and over current situations, that could damage the converter, the transformer or the load, it is necessary to find an operation point that assure the desired output voltage in spite of the load condition. This can done adjusting the frequency response of the transformer adding an external inductance, together with selecting the switching frequency to get stable output voltage independently of the load.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=High-voltage%20transformer" title="High-voltage transformer">High-voltage transformer</a>, <a href="https://publications.waset.org/search?q=Resonant%20converter" title=" Resonant converter"> Resonant converter</a>, <a href="https://publications.waset.org/search?q=Softcommutation." title=" Softcommutation."> Softcommutation.</a> </p> <a href="https://publications.waset.org/9999994/high-voltage-resonant-converter-with-extreme-load-variation-design-criteria-and-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9999994/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9999994/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9999994/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9999994/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9999994/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9999994/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9999994/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9999994/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9999994/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9999994/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9999994.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3068</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2506</span> PI Control for Positive Output Elementary Super Lift Luo Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=K.%20Ramash%20Kumar">K.

It runs at turbine speed and it is connected to a three phase electrical power grid which has its own frequency different from turbine frequency. In this regard the set composed of a four phase synchronous generator and a natural commutated matrix converter (NCMC) made with thyristors, is called active generator. It replaces a classical mechanical gearbox which introduces many drawbacks. The main idea in this article is the presentation of frequency control at grid side when turbine runs at variable speed. Frequency control has been done by linear and step variations of the turbine speed. Relation between turbine speed (frequency) and main grid zero sequence voltage frequency is presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Power%20Generation" title="Power Generation">Power Generation</a>, <a href="https://publications.waset.org/search?q=Energy%20Conversion" title=" Energy Conversion"> Energy Conversion</a>, <a href="https://publications.waset.org/search?q=FrequencyControl" title=" FrequencyControl"> FrequencyControl</a>, <a href="https://publications.waset.org/search?q=Matrix%20Converter." title=" Matrix Converter."> Matrix Converter.</a> </p> <a href="https://publications.waset.org/11160/turbine-speed-variation-study-in-gas-power-plant-for-an-active-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11160/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11160/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11160/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11160/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11160/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11160/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11160/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11160/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11160/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11160/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11160.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1897</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2502</span> Design and Control of DC-DC Converter for the Military Application Fuel Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Tae-Yeong%20Lee">Tae-Yeong Lee</a>, <a href="https://publications.waset.org/search?q=Eun-Ju%20Yoo"> Eun-Ju Yoo</a>, <a href="https://publications.waset.org/search?q=Won-Yeong%20Choi"> Won-Yeong Choi</a>, <a href="https://publications.waset.org/search?q=Young-Woo%20Park"> Young-Woo Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a 24 watts SEPIC converter design and control using microprocessor.

With the increase of switching frequency of digitally-controlled DC-DC converter, the DPWM with higher time resolution is required. In this paper, a 15-bits DPWM with three-level hybrid structure is presented; the first level is composed of a7-bits counter and a comparator, the second one is a 5-bits delay line, and the third one is a 3-bits digital dither. The presented DPWM is designed and implemented using the PLL megafunction of FPGA (Field Programmable Gate Arrays), and the required frequency of clock signal is 128 times of switching frequency. The simulation results show that, for the switching frequency of 2 MHz, a DPWM which has the time resolution of 15 ps is achieved using a maximum clock frequency of 256MHz. The designed DPWM in this paper is especially useful for high-frequency digitally-controlled DC-DC switching converters.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=DPWM" title="DPWM">DPWM</a>, <a href="https://publications.waset.org/search?q=PLL%20megafunction" title=" PLL megafunction"> PLL megafunction</a>, <a href="https://publications.waset.org/search?q=FPGA" title=" FPGA"> FPGA</a>, <a href="https://publications.waset.org/search?q=time%20resolution" title=" time resolution"> time resolution</a>, <a href="https://publications.waset.org/search?q=digitally-controlled%20DC-DC%20switching%20converter." title=" digitally-controlled DC-DC switching converter."> digitally-controlled DC-DC switching converter.</a> </p> <a href="https://publications.waset.org/10005808/a-high-time-resolution-digital-pulse-width-modulator-based-on-field-programmable-gate-arrays-phase-locked-loop-megafunction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10005808/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10005808/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10005808/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10005808/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10005808/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10005808/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10005808/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10005808/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10005808/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10005808/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10005808.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1244</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2499</span> A Single Switch High Step-Up DC/DC Converter with Zero Current Switching Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Rahil%20Samani">Rahil Samani</a>, <a href="https://publications.waset.org/search?q=Saeed%20Soleimani"> Saeed Soleimani</a>, <a href="https://publications.waset.org/search?q=Ehsan%20Adib"> Ehsan Adib</a>, <a href="https://publications.waset.org/search?q=Majid%20Pahlevani"> Majid Pahlevani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an inverting high step-up DC/DC converter. Basically, this high step-up DC/DC converter is an appealing interface for solar applications. The proposed topology takes advantage of using coupled inductors. Due to the leakage inductances of these coupled inductors, the power MOSFET has the zero current switching (ZCS) condition, which results in decreased switching losses. This will substantially improve the overall efficiency of the power converter. Furthermore, employing coupled inductors has led to a higher voltage gain. Theoretical analysis and experimental results of a 100W 20V/220V prototype are presented to verify the superior performance of the proposed DC/DC converter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Coupled%20inductors" title="Coupled inductors">Coupled inductors</a>, <a href="https://publications.waset.org/search?q=high%20step-up%20DC%2FDC%20converter" title=" high step-up DC/DC converter"> high step-up DC/DC converter</a>, <a href="https://publications.waset.org/search?q=zero-current%20switching" title=" zero-current switching"> zero-current switching</a>, <a href="https://publications.waset.org/search?q=cuk%20converter" title=" cuk converter"> cuk converter</a>, <a href="https://publications.waset.org/search?q=sepic%20converter." title=" sepic converter."> sepic converter.</a> </p> <a href="https://publications.waset.org/10010407/a-single-switch-high-step-up-dcdc-converter-with-zero-current-switching-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10010407/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10010407/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10010407/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10010407/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10010407/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10010407/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10010407/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10010407/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10010407/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10010407/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10010407.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">724</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2498</span> Zero Voltage Switched Full Bridge Converters for the Battery Charger of Electric Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Rizwan%20Ullah">Rizwan Ullah</a>, <a href="https://publications.waset.org/search?q=Abdar%20Ali"> Abdar Ali</a>, <a href="https://publications.waset.org/search?q=Zahid%20Ullah"> Zahid Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper illustrates the study of three isolated zero voltage switched (ZVS) PWM full bridge (FB) converters to charge the high voltage battery in the charger of electric vehicle (EV). EV battery chargers have several challenges such as high efficiency, high reliability, low cost, isolation, and high power density. The cost of magnetic and filter components in the battery charger is reduced when switching frequency is increased. The increase in the switching frequency increases switching losses. ZVS is used to reduce switching losses and to operate the converter in the battery charger at high frequency. The performance of each of the three converters is evaluated on the basis of ZVS range, dead times of the switches, conduction losses of switches, circulating current stress, circulating energy, duty cycle loss, and efficiency. The limitations and merits of each PWM FB converter are reviewed. The converter with broader ZVS range, high efficiency and low switch stresses is selected for battery charger applications in EV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Electric%20vehicle" title="Electric vehicle">Electric vehicle</a>, <a href="https://publications.waset.org/search?q=PWM%20FB%20converter" title=" PWM FB converter"> PWM FB converter</a>, <a href="https://publications.waset.org/search?q=zero%20voltage%0D%0Aswitching" title=" zero voltage switching"> zero voltage switching</a>, <a href="https://publications.waset.org/search?q=circulating%20energy" title=" circulating energy"> circulating energy</a>, <a href="https://publications.waset.org/search?q=duty%20cycle%20loss" title=" duty cycle loss"> duty cycle loss</a>, <a href="https://publications.waset.org/search?q=battery%20charger." title=" battery charger."> battery charger.</a> </p> <a href="https://publications.waset.org/10005329/zero-voltage-switched-full-bridge-converters-for-the-battery-charger-of-electric-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10005329/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10005329/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10005329/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10005329/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10005329/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10005329/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10005329/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10005329/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10005329/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10005329/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10005329.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2429</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2497</span> ZVZCT PWM Boost DC-DC Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=%C4%B0smail%20Aksoy">İsmail Aksoy</a>, <a href="https://publications.waset.org/search?q=Hac%C4%B1%20Bodur"> Hacı Bodur</a>, <a href="https://publications.waset.org/search?q=Nihan%20Alt%C4%B1ntas"> Nihan Altıntas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces a boost converter with a new active snubber cell. In this circuit, all of the semiconductor components in the converter softly turns on and turns off with the help of the active snubber cell.

The main feature of proposed converter is that the extra voltage stresses do not occur on the main switches and main diodes. Also, the current stress on the main switch is acceptable level. Moreover, the proposed converter can operates under light load conditions and wide input line voltage. In this study, the operating principle of the proposed converter is presented and its operation is verified with the Proteus simulation software for a 1 kW and 100 kHz model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Active%20snubber%20cell" title="Active snubber cell">Active snubber cell</a>, <a href="https://publications.waset.org/search?q=boost%20converter" title=" boost converter"> boost converter</a>, <a href="https://publications.waset.org/search?q=zero%20current%0D%0Aswitching" title=" zero current switching"> zero current switching</a>, <a href="https://publications.waset.org/search?q=zero%20voltage%20switching." title=" zero voltage switching."> zero voltage switching.</a> </p> <a href="https://publications.waset.org/10002137/zvzct-pwm-boost-dc-dc-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10002137/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10002137/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10002137/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10002137/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10002137/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10002137/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10002137/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10002137/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10002137/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10002137/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10002137.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2498</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2496</span> A Parallel Implementation of the Reverse Converter for the Moduli Set {2n, 2n–1, 2n–1–1}</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Mehdi%20Hosseinzadeh">Mehdi Hosseinzadeh</a>, <a href="https://publications.waset.org/search?q=Amir%20Sabbagh%20Molahosseini"> Amir Sabbagh Molahosseini</a>, <a href="https://publications.waset.org/search?q=Keivan%20Navi"> Keivan Navi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, a new reverse converter for the moduli set {2n, 2n–1, 2n–1–1} is presented.

First, it shows a buck-boost converter with an H-bridge, which requires few components (three switches, two diodes, one inductor and one capacitor) to convert AC input to DC output directly. This circuit can handle a wide range of output voltage. Second, a direct AC-DC buck converter is proposed for lower output voltage applications. This circuit is analyzed with output voltage of 12V. We describe circuit topologies, operation principles and simulation results for both circuits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=AC-DC%20converter" title="AC-DC converter">AC-DC converter</a>, <a href="https://publications.waset.org/search?q=Buck-boost%20converter" title=" Buck-boost converter"> Buck-boost converter</a>, <a href="https://publications.waset.org/search?q=Buck%0Aconverter" title=" Buck converter"> Buck converter</a>, <a href="https://publications.waset.org/search?q=PFC" title=" PFC"> PFC</a>, <a href="https://publications.waset.org/search?q=BCM%20PFC%20circuit." title=" BCM PFC circuit."> BCM PFC circuit.</a> </p> <a href="https://publications.waset.org/8775/non-isolated-direct-ac-dc-converter-design-with-bcm-pfc-circuit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/8775/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/8775/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/8775/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/8775/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/8775/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/8775/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/8775/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/8775/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/8775/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/8775/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/8775.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">4792</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2494</span> Digital Power Management Hardware Realization Using FPGA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kar%20Foo%20Chong">Kar Foo Chong</a>, <a href="https://publications.waset.org/search?q=Andreas%20Lee%20Astuti"> Andreas Lee Astuti</a>, <a href="https://publications.waset.org/search?q=Pradeep%20K.%20Gopalakrishnan"> Pradeep K.

Besliya Angel </a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Photovoltaic (PV) energy is one of the most important renewable energy sources. Maximum Power Point Tracking (MPPT) techniques should be used in photovoltaic systems to maximize the PV panel output power by tracking continuously the maximum power point which depends on panel’s temperature and on irradiance conditions. Incremental conductance control method has been used as MPPT algorithm. The methodology is based on connecting a pulse width modulated dc/dc SEPIC converter, which is controlled by a microprocessor based unit. The SEPIC converter is one of the buck-boost converters which maintain the output voltage as constant irrespective of the solar isolation level. By adjusting the switching frequency of the converter the maximum power point has been achieved. The main difference between the method used in the proposed MPPT systems and other technique used in the past is that PV array output power is used to directly control the dc/dc converter thus reducing the complexity of the system. The resulting system has high efficiency, low cost and can be easily modified. The tracking capability has been verified experimentally with a 10 W solar panel under a controlled experimental setup. The SEPIC converter and their control strategies has been analyzed and simulated using Simulink/Matlab software.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Maximum%20Power%20Point%20Tracking" title="Maximum Power Point Tracking">Maximum Power Point Tracking</a>, <a href="https://publications.waset.org/search?q=Microprocessor" title=" Microprocessor"> Microprocessor</a>, <a href="https://publications.waset.org/search?q=PV%20Module" title=" PV Module"> PV Module</a>, <a href="https://publications.waset.org/search?q=SEPIC%20Converter." title=" SEPIC Converter."> SEPIC Converter.</a> </p> <a href="https://publications.waset.org/9997866/a-maximum-power-point-tracker-for-pv-panels-using-sepic-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9997866/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9997866/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9997866/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9997866/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9997866/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9997866/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9997866/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9997866/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9997866/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9997866/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9997866.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">5969</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2488</span> Analysis and Design of Inductive Power Transfer Systems for Automotive Battery Charging Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Wahab%20Ali%20Shah">Wahab Ali Shah</a>, <a href="https://publications.waset.org/search?q=Junjia%20He"> Junjia He </a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Transferring electrical power without any wiring has been a dream since late 19<sup>th</sup> century. There were some advances in this area as to know more about microwave systems. However, this subject has recently become very attractive due to their practiScal systems. There are low power applications such as charging the batteries of contactless tooth brushes or implanted devices, and higher power applications such as charging the batteries of electrical automobiles or buses. In the first group of applications operating frequencies are in microwave range while the frequency is lower in high power applications. In the latter, the concept is also called inductive power transfer. The aim of the paper is to have an overview of the inductive power transfer for electrical vehicles with a special concentration on coil design and power converter simulation for static charging. Coil design is very important for an efficient and safe power transfer. Coil design is one of the most critical tasks. Power converters are used in both side of the system. The converter on the primary side is used to generate a high frequency voltage to excite the primary coil. The purpose of the converter in the secondary is to rectify the voltage transferred from the primary to charge the battery. In this paper, an inductive power transfer system is studied. Inductive power transfer is a promising technology with several possible applications. Operation principles of these systems are explained, and components of the system are described. Finally, a single phase 2 kW system was simulated and results were presented. The work presented in this paper is just an introduction to the concept. A reformed compensation network based on traditional inductor-capacitor-inductor (LCL) topology is proposed to realize robust reaction to large coupling variation that is common in dynamic wireless charging application. In the future, this type compensation should be studied. Also, comparison of different compensation topologies should be done for the same power level.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Coil%20design" title="Coil design">Coil design</a>, <a href="https://publications.waset.org/search?q=contactless%20charging" title=" contactless charging"> contactless charging</a>, <a href="https://publications.waset.org/search?q=electrical%20automobiles" title=" electrical automobiles"> electrical automobiles</a>, <a href="https://publications.waset.org/search?q=inductive%20power%20transfer" title=" inductive power transfer"> inductive power transfer</a>, <a href="https://publications.waset.org/search?q=operating%20frequency." title=" operating frequency.

High frequency isolated Cuk converters are used as a modular dc-dc converter in Discontinuous Conduction Mode (DCM) of operation of Power Factor Correction. The aim of this paper is to simplify the program complexity of the controller by reducing the number of fuzzy sets of the Membership Functions (MFs) and to improve the efficiency and to eliminate the power quality problems. The output of Fuzzy controller is compared with High frequency triangular wave to generate PWM gating signals of Cuk converter. The proposed topologies are designed to work in Discontinuous Conduction Mode (DCM) to achieve a unity power factor and low total harmonic distortion of the input current. The Fuzzy Logic Controller gives additional advantages such as accurate result, uncertainty and imprecision and automatic control circuitry.

In this paper, VSCs are designed in quasi multi-pulse form in which GTOs are triggered only once per cycle in PSCAD/EMTDC. The design details of VSCs as well as gate switching circuits and controllers are fully represented.

This paper provides the comparative results of these two different transformers in terms of their resistances, self, leakage, mutual inductances, coupling coefficient and also their energy efficiencies. The operating regions for optimal performance of these transformers for power transfer applications are determined. These transformers were tested for the output power levels of about 30 Watts within the input voltage range of 12-50 Vrms. The energy efficiency for these step down transformers is observed to be in the range of 90%-97% in MHz frequency region. <p class="card-text"><strong>Keywords:</strong> <a
